Example Question #1 : How To Add Even Numbers
The sum of seven consecutive even integers is 0.
Column A: The product of the seven integers
Column B: 2
The relationship cannot be determined from the given information.
The two quantities are equal.
Column B is greater.
Column A is greater.
Column B is greater.
For the sum of 7 consecutive even integers to be zero, the only sequence possible is –6, –4, –2, 0, 2, 4, 6. This can be determined algebraically by assigning the lowest number in the sequence to be “y” and adding 2 for each consecutive even integer, and then setting this equal to zero.
y, y + 2, y + 4, y + 6 . . .
The product of any number and 0 is 0.
Therefore, column B must be greater.

A good note about adding even numbers--any even numbers--is that if you add two even numbers, their sum will ALWAYS be an even number.
Example Question #1 : Even / Odd Numbers
Choose the answer below which best solves the following problem:
To deal with a problem with this many digits, often the best strategy is to line up one number over the other, then add the places one at a time. Don't forget to carry a one every time the addition goes over ten. Also, note that any time you add two even numbers, their sum will ALWAYS be an even number.
